The wine mostly went into the sauce but mom liked to have a glass or two during prep as well. ;-)
I got a recipe from a friend for a pound cake. She listed under ingredients: one bottle of wine that you like. I wondered why till I read the directions. Open bottle of wine, pour a good, healthy glassful and drink. Repeat. Repeat. Repeat. She guaranteed that the pound cake was delicious. If not, you didn’t care by then if you repeated enough. LOL
